In this episode of Everyday Health Stories, Dr. Kota Reddy and Anna uncover the science behind sauna therapy and its potential role in dementia prevention. They explore the remarkable case of Doug Whitney, a man genetically destined for early-onset Alzheimer’s who has remained cognitively sharp well beyond his expected age of decline. Through compelling research from Finland, they discuss how heat shock proteins—activated by regular sauna use—may protect the brain by preventing the spread of harmful tau proteins. Listeners will learn about the 50% reduction in dementia risk linked to sauna use, the cardiovascular and anti-inflammatory benefits of heat therapy, and practical recommendations for incorporating sauna sessions into a healthy routine.
